Ok so here's the update. Everything is bolted up, filled the fluids, installed the DBW with pedal, TAC, and pigtail. I have the 5.3l fuse block installed and the engine to harness plugs hooked up. I printed out ALLDATA plug schematics for both motor harnesses to compare pins. 90% of the pin's location, color, circuit and function are the same. My question is can someone who's done this swap please throw me done advice on the wiring part. I'm officially stuck.
